OBJECTIVE To describe rank reversal as a source of inconsistent interpretation intrinsic to indirect comparison (Bucher HC, Guyatt GH, Griffith LE, Walter SD. The results of direct and indirect treatment comparisons in meta-analysis of randomized controlled trials. J Clin Epi 1997;50:683-91) of treatments and to propose best practice. METHODS We prove our(More)
We demonstrate how to apply regression risk analysis to compute risk ratios and risk differences from logistic regression models using complex survey data. We validate the use of regression risk analysis for complex survey design. First, we derive formulas for adjusted risk ratios (ARRs) and adjusted risk differences (ARDs) adjusted for weighting,(More)
These diseases are classified together as the seronegative spondyloarthritides. They are characterized by an association with the cell surface antigen HLA-B27, sacroilitis and spondylitis, inflammatory peripheral arthritis, enthesopathy (abnormalities in ligamentous attachments), and the absence of rheumatoid factor. Extra-articular complications are(More)
Light-induced structural changes of chloroplasts and their lamellae were studied in leaves of Pisum sativum L., cv. Blue Bantam, using electron microscopy. Upon illumination of 14-day-old plants with 2000 lux, the chloroplasts decreased in thickness by about 23% with an accompanying increase in electron scattering by the stroma. Concomitantly, the average(More)
